The linkage 15a3 of the rocker heat exchange unit 15a of parallel configuration uses column gear mechanism 15a3b or crank link mechanism 15a3c as preferring, the column gear mechanism is three sets of, each rocker heat exchange unit 15a is provided with one set, each set includes gear motor 15a31, driving column gear 15a34 fixed on the gear motor output shaft, driven column gear 15a35 fixed on the central shaft of two rocker energy storage cores 15a2 and engaged with the driving column gear respectively, the driving column gear drives two driven column gears to deflect in the same direction, and the two driven column gears are sector local gears. As shown in fig. 6. The three sets of column gear mechanisms intermittently rotate in the same period, but the action time of the three sets of column gear mechanisms is mutually clamped, for example, the action time is staggered by one third period, so that the short-term influence on the air volume in the deflection process of the wane energy storage core 15a2 is not superposed together, and the air volume of the whole machine cannot obviously change.

The above-mentioned gear mechanism 15a3b can also be changed into a crank link mechanism 15a3c, which comprises a speed reducing motor 15a31, a crank 15a37 fixed on the shaft of the speed reducing motor, a connecting rod 15a38 hinged with the crank and a synchronizing rod 15a39 hinged with the connecting rod, wherein the synchronizing rod is hinged with the frame of 6 rocker energy storage cores 15a2 to keep them synchronously deflected, as shown in fig. 7. When the rocker-type energy storage device works, the speed reduction motor rotates in a reciprocating mode, and the crank connecting rod drives the rocker-type energy storage cores 15a2 to deflect in the same direction. The advantage of the gear mechanism is its compactness, while the advantage of the crank-link mechanism lies in the inherent kinematics and dynamics, i.e. the starting and ending points of the yaw motion are naturally decelerated, acting as a buffer and a force-increasing effect, resulting in a silent reversal and a sufficiently high sealing pressure. The 6 wane energy storage cores of the mechanism act simultaneously, so that the structure is simpler, but the air quantity fluctuation is larger during reversing, and the mechanism is used for occasions with low requirements on noise.
